RELlSHlNG-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 223,500, dated January13, 1880.

V Application filed May 3, 1879.

To all whom it may concern Be it-known that I, EBENEZER R. GAY, ofDubuque, in the county of Dubuque and State of Iowa, have invented a newand Improved Relishing-Machine, of which the following is aspecification.

My invention relates to a relishing or tenonfinishing machine for use onrails for doors, blinds, panels, or other wood-work having rails withtenons and a groove or rabbet for panels. In such work, when the grooveis not as wide as the tenon is thick, or does not have the same face asthe tenon, a rib or projection is left, which has to be removed, andmyimproved machine is adapted for such operation.

I make use of a reciprocating bit and a knife fitted to actsimultaneously and in directions at right angles to each other upon therail that is placed on a bed and held by an adjustable gage and clamps;and the machine is fitted for operation by foot or other power. 1

In the accompanying drawings, Figure l is Fig. 2 is a verticaltransverse section on line 00 :v of Fig. 1.

Similar letters of reference indicate correspondin g parts.

A is the frame of the machine, on which is fixed the bed or table B.Beneath the bed B, in suitable slideways a, is fitted a vertical slideor head, I), that carries the cutter c. This cutter c is adjustable onslide b, to compensate for wear, and works through a slot in bed B. Uponbed B is an adjustable box, cl, formed with an aperture for receivingand supporting the horizontally-sliding bit 6. The shape of thecutting-point of e is adapted for the particular work to be done, andthe bit may be changed as required. The cutters are simultaneouslyoperated by a main lever, j, that is 7 connected by a crank with ashaft, that is driven by suitable power, or, when the machine isoperated by foot, lever f will be conand bit 6 moved inward towardcutter c at the same moment. A spring, Z, is fitted to withdraw thecutters when the machine is operated by foot.

Upon bed B is a gage, m, attached adjustably by the lugs n. This gagesustains the rail against the action of bit 6, and its positionregulates the depth to which 0 outs. A fixed clamp, 0, also on bed B,holds the end of the rail down upon the bed against cutter c. A gage,1), adjustable on bed B lengthwise of the' rail, abuts against theshoulder of the tenon to regulate the position of the out made by bit 0.

In Fig. 3 is represented a rail, q, formed with a square-shoulderedtenon, r, and groove 8. The groove 8 being narrower than the tenon, thenojccting edges if from the shoulder to the end of the tenon have to beremoved. This is the simplest form of rail, and in this case the bit 0would have a straight cuttingedge, and cut across on line with theshoulders to the depth of the groove. If the shoulder be in the form ofan ogee the bit will correspond in shape, and in some cases the railsare rabbeted instead of grooved, and formed with an ogee shoulder.

The machine is adapted for any work of this character, and the relishingis done with rapidity and much more economically than it can be done byhand.

The machine is simple and durable, and requires but a small amount ofpower to operate it.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. The combination, with the bed B, slide 1), havingvertical cutter c, and bit 6 in block d,

- of the slotted elbow-lever 7c and the slot-ted lever t, pivoted nearits middle to a pendant of franie, said levers being each connected atone end with the actuating-lever], as shown and described.

2. The combination, with cutter c and bit 6, of the adjustable gages lapand fixed clamp 0, as and for the purposes specified.
